Compared Castrol Edge vs Edge Extended Performance

[double vanos]

Looking at the msds sheets and what stuck out was the Castrol EDGE Extended Performance has an additive described as :Fatty acids, tallow, compounds with triethanolamine.

And just what does all this mean? Almost sounds like they're hanging around the butcher shop for the cut off fat.

Please discuss.

It's a bio-ester (group V), much like what G-Oil and Renewable Lube are using. In fact, G-Oil is using tallow-derived oils too. I think RLI is plant-based.

I see it as a good thing: it's a modern formula.

From Wikipedia:
Triethanolamine is used primarily as an emulsifier and surfactant. It is a common ingredient in formulations used for both industrial and consumer products. The triethanolamine neutralizes fatty acids, adjusts and buffers the pH, and solubilises oils and other ingredients that are not completely soluble in water. Some common products in which triethanolamine is found are liquid laundry detergents, dishwashing liquids, general cleaners, hand cleaners, polishes, metalworking fluids, paints, shaving cream and printing inks.

Sounds like it comes with its own dose of Auto RX!!!

Yes, those fatty acids are from the remnants of the beef industry. My office is next door to a Sanimax that renders the beef fat into the tallow product that is used in making the base oil, among many other products.

It is the worst stench in the world, and most days we are down wind from them.
